04.) Design a 4-R bias network for an NMOS transistor (assume K = 15mA/V² and Vy = 2.5V), and design for center-bias and a drain current of Ipo = 4mA. Assume you have a single 9V supply available (let Vee = 0V!).

Create a K-map for (A + B’)(A + B + C’)(B + C)

Can you help give a detailed step by step explanation of the math in this solution:

R148 R149 R150 If R148 is 18 Ohms, R149 is 13 Ohms, R150 is 25 Ohms, and there is 4 Amps flowing through R150, what is the current through R148? Please show 3 decimal places and don't include units in your answer (i.e. don't include A in your answer).
